For the inventive positioning device 8 branch line 41b to the compressed air connection 43 ströist it irrelevant whether the service carriage 4 men motorbikes. The compressed air connection 43 is driven risch at the upper end and automatically attached to a pipe 44 to be serviced, which is called up in the mounting block of the work site, or whether the war- 32 is slidably guided. The lower end of the processing carriage 4 is moved by hand along the machine. 5 Pipe 44 is moved over a strut 45 and a rod 46. A maintenance trolley that can be moved, for example by hand, on the piston rod 47 of the piston-cylinder unit is attached by the operator 42. When pressure is applied to the cylinder while patrolling along the machine, the piston-cylinder unit is taken along with the compressed air. On the spindle, on which a thread breakage took place. Conclusion 43 about the tube 44, the strut 45 and the tangential drive belt 12, at the top of the rod 46, are in abutment position against the, for example, described in DT-OS 2130 762 - lower moved away of the spindle rotor 9 or the yarn planes manner and the spindle rotor 9 off of disc 36 down, having been at the same time slows down, the operator turns on the compressed air through the branch line 41 b and the pipe has a shift lever 20 of the valve 19, on the 44 to the compressed air connection 43 flows.
Line 21 is connected to the hollow frame 15 in the underside of the spindle rotor or the frame 18 which is filled with compressed air. As a result, compressed air flows through the storage disk 36, a connection opening 48 is made in the line 22 connected to the valve 19, which, in the manner described in DT-OS 2 130 762, by means of the two pneumatic piston-cylinder units, results in units 15 arranged on the spindle rotor be pressurized with compressed air. Neten compressed air threading device leads. The piston rods of this piston 20 closing opening 48 are attached in such a way that they, cylinder units 15 extended, the positioning device 8 after the spindle rotor 9 is raised through cooperation, so that they are connected to the locking pin 37 and stop 38 has been stopped in its vorbe-positioning the carriage 4 with the roller 14 correct position, can interact precisely (see the patent application above the free opening of the compressed air connection-P 23 17 052.7 of the same applicant). 25 ses 43 lies.

Then the switch 23 is actuated, whereby the compressed air connection 43 is opened after AnVentil 24, so that compressed air by holding the spindle rotor 9 from the piston-cylinder open, pneumatically controlled valve 26 in the der-unit 42 in the predetermined position against Compressed air line 27 flows in.
